The CTS-V with its 6.2 liter supercharged LSA V8 is a very potent car. In a drag race it is expected to run low 12's but what happens in the video below versus a Renntech tuned DCT 335is goes to show how big of an effect conditions can have especially on a positive displacement supercharged car generating a lot of heat such as the CTS-V. This run took place at PBIR (Palm Beach International Raceway) in 85 degree weather and 1800+ Density Altitude.

The 335 manages a 12.4@113.86 to the CTS-V's 12.8@112.41. The CTS-V and 335 are both capable of more but in hot weather that is what they run. Many people make the mistake of taking a fast time (such as a Z06 running a 10 at MIR in the winter) and thinking the car is always capable of it. The weather has a huge effect on performance.

BuraQ have you added a better IC for your car? I believe if u havent and would so , diffinetely your times would be better than the V, dont get me wrong I love (the Vs)them but they are very rare here in Puerto Rico. I think Ive only seen a couple here, arent they running the same engine the Vette is?

I am using the Dinan FMIC which has a 93% volume increase over the stock FMIC. The Dinan FMIC is a modified Spearco untilizing their W.A.V.E. Technology bar and plate cores.

The same event day my best ET was 12.2 in that heat. I was even able to trap 115 which was all about finding where to shift in those weather conditions.

Here is another video from the same day running against a JB4 Map 7 E90 / DCI /DPs/E85 mix, first timer on track. On this day I was running on stock DPs

I think I was the only BMW there that didnt get a limp mode from that heat. Mostly everyone I spoke to had limp mode issues
